To all whom ibm/ay concern.-

Be itknown 'that I, JOHN HENRY MC- GUIRE,Ia citizen of the United States, and a resident of Heuvelton, inthe county of St. Lawrence vand State of New York, have invented a new and Improved Stanchion, of I which the following'is a full, clear, and exact description. l

This invention relates to certain im rove? ments in 'stanchions for cattle; and t e object thereof is to provide a'stanchion which may be moved backward or forward or rotated upon a pivot by the 'animal secured therein.

AAf'urther object of the invention is to provide certain improvements in the means for holding th'ebars of the stanchion in anA open or-elosedposition and prevent them from being turned on fthepivot when in the open position.

Reference is to'be had to the accompany-l ing drawings, forming appart of this specii' cation," in lwhich similar characters of reference indicate corresponding parts in all the figures, in which- "Figure 1 is'a front elevation of my im Fig. 2 is a detail showreferred method of securing the lower end) thereof in place. Fi 3 is a plan viewof the'stanchion when in t e closed posi'tion. Fig. 4 is a view'similar to Fig. 3, but showing the stanchion in the open position. Fig. '5 is a central vertical section through the parts as shown in Figs, and Fig. 6 is an inverted lan view of one ofthe-overhead pi'voted b ocks or plates and on the line 6 6 of My improved stanchion comprises two substantially vertical bars 1, pivoted at the lower ends thereof between ytwo cross members 2,'which latter are rigidly secured to the'4 A opposite` sides of a central block 3.

This b ook hasV a vertical pivot-bolt 4 extending downwardly therethrough and through a slot 5 in a metal bar 6, secured to the floor or in any other suitable manner to a stationary The bolt 4 is provided with a nut 7 below the'slot '5, so that the block 3, carrying thelower ends of the two substantially vertical bars 1, may move forward andl backward through the slot to accommodate the stanchion to certain InofveY ments of the animal held between the sub.-

stantially vertical bars l.. ,Various other,` means within the scope -of the appended .Specification of Letters Patent.

claims may be employed for pivotallyv securing the lower ends and at the same time per'- mitting the ends to be moved forward and backward, although the form illustratedA in the drawings is the best form known to myself at present.

The upper ends of the bars extend between two metal plates 8, which latter are spaced apart a distance equal to the thickness of the bar by means of a centrally-located block'9 and by spacing-pins 10 at theI outery ends of the plates. A; pivot-bolt 11 extends through to an overhead support 13 in thesame Inanner as the plate 6 1s secured to the flooror `the central spacing-block 9 and up through a slot in a plate 12, similar to 'the botto-rn Iplate 6. The plate 12 is preferably 'secured lower support 14, and the nut `15 on the bolt Amay move backward and forward though the slot in the late. In Fig. 5 I have shown a sli htly-mo ified form of construction, inI

whic the pivot-bolt 11 extends througha slot in the overhead supportv13 and is pro-4 vided with washers above and -below said; support and a nut 16 and locking-nut 17 above the upper washer, whereby the bolt,

may freely rotate and at lthe same time 'ma be moved. backward and forward through', the slot. y'

The plates 8 are 'provided at their` u perI .edges with horizontal anges 18, whichflbrm a support for the locking-bar 19. This locking-bar 19 is pivotedon the bolt l1, and its i ends are provided with notches 20, adapted: to enga e`the bars, 1 adjacent their upperifo ends an hold the bars at a definite distance' tapered, as clearly indicated in Figs. 3 and 4, I'

apart. The end portions f the-locking-bar 19, which extend beyond thesenotches, are"P gether the locking-bar is pushed aside until the end's of the bars drop into the notches 20. f

For causing the' two bars 1 1 to.moveff simultaneously "and to force the locking-halfV 19 lnto engagement therewith when theyare'flco brolight a sullicientdistance together, I pro-f1 vide aplate 21, pivotedbn the bolt 11 orf;`

upon a loose collar 22, mounted on said bolt-.Jij @l f andthe ends of this plate'21"arep i'votallyl connected t0,` connecting-links` 23, havingfg'a. ".loops at their outer ends which inclose thef` vertical bars 1.A ,Asone of the vertical'bar'sffy `is forced toward' 'the center the link -23',

causes the rotation ofthe plate 21, and this rotation drawsI ,onl the oppositel link 2,3 and r o Aresults in a similar'moveine'nt of the other bar 1, so that whichever one of the two vertical bars 1s moved` 1n any diiection a similar movement is given to the opposite bar. Fori"- preventing the plate 21 from twisting sidewise or becoming distorted by one end rising and the other end lowering, I provide a reinforced bracing-plate 24 of substantially the same shape as the plate 21 and bolted at the ends byl means of the rivets to wliichthe links 23 are pivoted but the central portion of the plate 24 is bowed' up# ward and, ivoted on the pivot-bolt 1.1 or lthe collar g2 yat-a point somewhat above the point at which vthe plate 21 is pivoted. This bulged portion preferably suppoits the lower washer when the lorm disclosed in Fig. is employed. The plate 21 rests upon the upper end of a coil-spring 25, which latter rests upon the locking-bar 19. (hie end 26 of the spring-coil engages with the locking bar 19, and the other end 27 engages with the plates 21 and 24. This spring tends to rotate the locking-bar 19 in respect to the vplate 24, so that said bar is always forced into engagement with the upper ends ol the bars 1, and the plates 21 and 24 are normally rotated to the position shown iii Fig. el, so that as soon as the locking-bar 19 is moved aside the barsl automatically separate to permit the animal 'to remove its head from between the bars; but as soon as the bars are forced together alter the animal has insorted its head between the bars the spring forces the locking-bar into sn'ch engagement with the vertical bars that the notches 20 engage with the latterk and hold them rigidly secured together.

As both the upper and the lower ends of the stanchion are pivoted to the stationary supports, it is of course evident that the animal may turn the stancliion at will, and thus freely move its head and shoulders. At the same time the stancliion may .be moved backward and l'orward to erinit the greatest freedom when the anima desires to lie down.

The overhead support 1.3 is preferably provided with blocks` or lates at each side of the support ior tiie pivotpiii, and each of these biocks or plates is provided with a divergent slot 29, as shown in Fig. 6, into which the upper ends' of the bars 1 may move when they are separated. As the inner ends oi' the blocks or plates 28 are farther apart than the upper ends of the bars 1 when the latter are in the closed position, the stianchion may be freely rotated` upon the pivot-pin 11; but when the staiicliion is .opened the upper ends ol' the bars 1 slide back within the grooves or slots in the plates or blocksQS` and the stancliion cannot then be rotated. Thus the staiicliioii when open is always in suoli a position that the animal may freely insert its head between the bars,

the spring then forces them apart into the,v

open position.

Preferably the pivotbolt which passes through the lower end of each upright is located at one side of the central line of the upright and a portion of each upright at its upper end where itis engaged by the lockingbar is cut away, as indicated in the drawing.A By this means the entire stancliion may be adjusted to tlnec diilereiit sizes to accommodate dilierent-sized animals without adding to or taking from the original stanehion.

"llie smaller size is made by having the larger side of each ol the uprioht parallel bars turned inward or toward tde aniinals neck. vThe next larger size is made by removing the bolt at the bottom ol' onevof the parallel upright bars and taking said bar out and replacing said bar with the opposit(` side toward the inside or aiiiinalls neck, The largest size is iliade by removing the bolt at thc bottom of both upright parallel bars and taking both bars ont and turning the outer side of each bar inward or toward the animals neck.

It is evident that the stanchion shown in the drawings involves only one embodiment of my invention and that various changes may be made without departing from the spirit of the saine.

Having thus described my invention, i claim as new and desire to secure by Letters .Pa-tenti 1. Li stanchioii, comprising two siibstan- L means for supporting the'lower ends thereof,
